Begin by sautéing shallots, tomatoes, and garlic in a bit of oil. Once the tomatoes develop blisters, gently crush them and then lower the heat. Incorporate vinegar, salt, and sugar, allowing the mixture to simmer until it reduces.
Cut the zucchini into strips and season the flesh with salt. Combine flour, baking soda, and water until a batter forms.
Dry the courgette slices, dip them in the batter, and shallow fry in oil for about a minute or two on each side until they turn golden and achieve a crispy texture.
Present your tomato relish on a plate, place the courgette fritti on top, and garnish with fresh basil, lemon, and a sprinkle of salt. Enjoy your flavorful dish!
